Review on 🪚 Irwin Tools Step Drill 16 Inch – Model 10220 by Viswanath Lopez

I was hoping this brand bit would be better. Its heavy shank is not suitable for a hammer drill and it is not hard enough to pierce a mower blade (hardened steel). If I just wanted to drill in mild steel I could get ones that are great for port freight or ones that fit my percussion tool. It's a good tool, but don't expect it to be anything special.
